Properties Of The Kα And Kβ Transitions From CuXX Through CuXXVIII And The Calculations Of The Hyperfine Structure Constants Of The First Subgroup Elements

Accurate transition data in highly ionized atom is important not only in astronomy and astrophysics but also in other scientific areas such as plasma physics. The hyperfine structure of an atomic energy levels is caused by the interaction between the electrons and the electromagnetic multipole moments of the nucleus. These electron-nuclear interactions can therefore serve in turn to probe details of the nuclear structure and may help in testing the validity of nuclear models.Transition properties of the Kαand Kβx-ray from CuXX through CuXXVIII have been calculated by using the active space method and the relativistic Multi-Configuration Dirac-Fock(MCDF) method. The contributions from Breit interaction, quantum electrodynamics(QED) corrections, and the nuclear mass corrections to the initial and final levels have been taken into account. The calculated values are compared with the other available data and are found to be in very good agreement with them. In this paper we give accurate transition properties from CuXX through CuXXVIII. These data provide reference value for level lifetime, charge state distribution and average ionization of copper plasma.The same methods have been employed to calculate the magnetic dipole hyperfine structure constant A and the electric quadrupole hyperfine structure constant B of neutral Cu, Ag and Au. The contributions from Breit interaction, quantum electrodynamics (QED) corrections, Core-Valence correlations, Core-Core correlations and Bohr-Weisskopf correction have been taken into account. The calculated values are compared with the other available data and are found to be in good agreement with them. In this paper we give the magnetic dipole hyperfine structure constant and the electric quadrupole hyperfine structure constant of 4s ²S_1/2,4p ²P_1/2 and ²P_3/2 of Cu, 5s ²S_1/2,5p ²P _1/2 and ²P_3/2 of Ag, 6s ²S_1/2,6p ^P_1/2 and ²P_3/2 of Au. The hyperfine splits of these ground states are also calculated .These data provide reference values in a variety of scientific applications, especially in atomic clock.The GraspVU package we used in our paper is an extension and modification of GRASP92 by Charlotte Froese Fischer and her collaborators in Vanderbilt University in America.
